Engine And Engine Cooling Problems of Toyota Tundra - part 2

-our Toyota Tundra hybrid suffered total catastrophic engine failure due to metal shavings found throughout the engine and oil system. This is the same issue that prompted NHTSA id number: 25v767000 recall of Toyota's v35a engines. The Tundra is available for inspection. -statement regarding safety put at risk by my husband: I felt a vibration from the engine compartment (seeming to come from the front right side) and then I suddenly lost complete power. I was traveling in the number one lane (the fast lane). I immediately put my hazards on and had to navigate to the number two lane and then over to the narrow shoulder under no power whatsoever. I had to navigate around multiple semi-trucks. This was a very dangerous situation and I barely got it over to the shoulder. If my teenage daughters were driving this car they likely wouldn't have been able to safely navigate it across two lanes with no power in the setting of multiple semi-trucks on a two-lane divided highway. Again, a very dangerous situation. I shut down the engine and waited five minutes and restarted it. Shifting into gear the warning indicator said 'hybrid system disconnected'. -the total catastrophic engine failure has been confirmed by the Toyota dealership. Th4ey confirmed multiple shavings of metal in the entire oil system and the engine has seized. He said that the engine needed to be replaced. -the Tundra has not been inspected by the manufacturer, police, insurance (yet) or others besides the Toyota dealership. -there were no warning lamps, messages, or other symptom of the pending catastrophic total engine failure.

On July 20, the vehicle experienced a catastrophic mechanical failure resulting in a total engine seizure while operating. The failure caused an immediate, sudden loss of motive power, forcing the vehicle to become completely immobilized on the interstate highway. This unexpected loss of propulsion created an immediate and severe highway crash hazard for myself and surrounding traffic. The vehicle was towed to an authorized Toyota dealership on July 20 under the 5-year/60,000-mile factory powertrain warranty. The vehicle has remained completely out of service since that date. The dealership has tentatively scheduled the engine repair and replacement to begin on August 24 or 25, meaning the vehicle will have been non-operational and out of service for over 35 consecutive days before repairs even commence.

Engine seized up just after completing a pass on 2 lane road with oncoming traffic approaching truck started shaking, warning lights illuminated and I lost all ability to accelerate. I was only able to crest a slight incline and safely get to the shoulder of the road due to momentum gained during passing. Toyota states hybrid models have locomotive ability after engine seizing, this is clearly not true. Had the seizing occurred while passing, it would have likely resulted in a head on collision. Dealer inspection confirmed engine seizing and noted metal shavings were observed on the dipstick.

Driving on the interstate and the truck surged very hard. The truck began to surge very hard and went into decreased speed mode. We were told by the dealer there is a TSB for the pcm. This decreased power caused the truck to not be able to travel over 25 mph in a 70 mph zone. This caused an unsafe situation.

The contact owns a 2023 Toyota Tundra. The contact received notifications of NHTSA campaign numbers: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling); however, the parts to complete the recall repairs were not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repairs. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

5/4/26 truck brough in for service, I raised concerns of hesitation from a rolling stop/complete stop. This hesitation had happened to me a dozen or so times since purchasing the truck new in August of 2024. I expressed to my service advisor that I experience a 2-3 second delay in acceleration with the truck simply not responding after I have pulled out in traffic from a rolling stop. My service advisor noted my concern and got with the service manager. The service manager took the time to ride along with me in hopes of duplicating the problem. We were not able to reproduce the hesitation. Inconclusive findings was my conclusion of that service. T-sb-0032-26 was issued two days later on 5/6/26 7/3/26 truck brought in for service, I shared with my service advisor that I discovered t-sb-0032-26 while reiterating my previous experiences. TSB was performed on the truck successfully according to my service conclusion report. 7/7/26 hesitation almost caused an accident. As I was crossing two way traffic, the truck hesitated. Traffic in both directions had to apply their brakes to avoid hitting me. This 2-3 second hesitation in acceleration creates a very unsettling moment. This is the kind of hesitation that could easily result in my getting rear-ended or t-boned in traffic. Other cars have to react to my truck not responding and slow down. If this causes an accident, I want this noted. I sent this information to my service advisor, the truck is going back to Toyota tonight for them to look into the computers history and see if they can find anything showing the hesitation. I even noted the date and time to my service advisor. Very interested to see what they do next.

I own a 2024 Toyota Tundra 1794 edition with approximately 37,000 miles. On or about xxx, while driving, the vehicle displayed a “check engine” warning, “reduced engine power” message, and the pre-collision system became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.

We were driving on [xxx] coming from [xxx] going to [xxx] pulling a trailer within weight limits when the engine went out. We had it towed and looked at a dealership in [xxx]. They said it would. Need engine replacement. We had it shipped to michigan spartan Toyota in lansing who quoted us 30k for the replacement. It is out od the warranty replacement. Toyota corporate said they wont do anything. Even though they recalled the non hybrid engines for the same reason. They wont replace the hybrid engines. We just bought this truck a month ago. Used. The car dealership wont take it back. We know out what we bought it for (36k) plus this engine replacement. Whixh no one will help with. We were not offered an extended warranty information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On April 7, 2026, at 5:00 pm, while driving, I noticed something unusual with my car, and it broke down on the side of the road, leaving me panicked and frightened. After the car stopped, I got out and looked at the engine from underneath; I saw engine oil spraying out of the engine. I then had the car towed to a safe location, and a few days later, I took it to the Toyota dealership.

While driving my 2024 Toyota Tundra, the check engine light illuminated and the vehicle suddenly experienced reduced engine power. I safely pulled over, shut the engine off, and restarted it. After restarting, the vehicle appeared to operate normally, but a diagnostic scan showed dtc p0300 (random/multiple cylinder misfire). On July 20, 2026, I brought the vehicle to an authorized Toyota dealer for inspection. During the inspection, the dealer found significant metal shavings in the engine oil, indicating a possible internal engine failure. Based on these findings, the dealer instructed me not to drive the vehicle and retained it at the dealership because they considered it unsafe to operate. My vehicle is already included in Toyota’s engine recall related to engine manufacturing defects. However, despite the dealer confirming the presence of significant metal shavings and advising that the vehicle should not be driven, no repair or resolution has been provided. The dealer has been unable to provide an estimated repair timeline or when the vehicle will be returned to service. The vehicle is available for inspection. No crash or injuries occurred. Prior to the incident, there were no warning signs or abnormal symptoms. The check engine light and reduced engine power occurred suddenly while driving. The unexpected loss of engine power created a significant safety risk, particularly while driving at highway speeds or in traffic. I am also concerned that an apparent internal engine failure occurred with little or no warning. In addition, because the dealer has retained the vehicle and no rental or alternate transportation has been provided, I have been left without transportation while waiting for a resolution.

2016 flex fuel Toyota Tundra with 118,00 miles was towed to Toyota dealer in las cruces with a no fuel issue. After the analysis it was determined the fuel pump over heated burning out conector and wiring ,but the pump was still working. According to Toyota TSB 0166-19 this is a problem the can arise if the alcohol fuel density id is not updated. I told the dealer to due repairs on vehicle even though a fuel pump was installed and reflashed at 114,000 miles. Viva Toyota of las cruses advicate stated that a reflash is all the vehiles needs and does not desire to change the alchol fuel density to updated id as per TSB-0166-19, so I am worried I will be operating a vehicle with a fuel pump that will over heat and burn out connectors again. I called Toyota complaints and they told me they cannot make a dealer do any repairs.

Complete catastrophic engine failure at 36,514 miles on July 2, 2026, while the vehicle was being driven. There were no warning lamps, messages, knocking, or other symptoms prior to the failure - a sudden and total loss of motive power while the vehicle was in motion, creating a serious risk of a crash. The vehicle was towed to a franchised Toyota dealership (hendrick Toyota concord, concord, nc), where the dealer confirmed the engine failure. The failure is consistent with the engine machining debris / #1 main bearing defect described in NHTSA recall nos. 24v-381 and 25v-767 and the related Toyota campaigns (25tb14/25ta14). As of this filing, the vehicle has been out of service at the dealership for more than 40 days with no replacement engine allocated and no repair date provided. A Toyota corporate case (#260805003088) is open. The vehicle and failed engine are available for inspection at the dealership.

This is the second time this has happened to my truck. I was driving on the freeway at about 30–40 mph when the truck suddenly shut off. It was very scary because I was in moving traffic. This time, several warning lights came on, but I didn’t have a chance to see what they were because I immediately started to panic. I had to bring the truck to a complete stop by applying the brakes and then shifting it into park. Once I did that, I pressed the start button, and the truck started back up. This incident has me very concerned because it’s now happened twice. I’m worried that if it happens again, I could be rear-ended and seriously injured. I believe this is a significant safety issue that needs to be investigated and repaired as soon as possible. This is the second time this has happened to my truck.

Was waiting for the traffic light to turn green. Vehicle in drive with foot on brake. The traffic light turned green, I took my foot off the brakes and pushed on the accelerator. Nothin happened. I saw another vehicle approaching at a high rate of speed behind me so I continued to mash on the accelerator. Right before being hit by the car behind me my vehicle lurched forward a few feet then stopped again. I looked at the dash display and saw a "hybrid system malfunction" warning. Because of the traffic situation/location it was not safe to just sit in the road so I continued to pump on the accelerator. Each pumped moved the vehicle forward a couple of feet. I did not turn of the engine because I was unsure what would happen so I continued to do that for about a mile or so until I could get to a safe place to pull over. During this time, I almost got rear-ended and side-swiped several times. Once stopped I attempted to start the vehicle several times and got the "hybrid system malfunction" display and the vehicle would not start. I waited for about an hour with the vehicle off and restarted the engine. I stayed off the freeway and took backroads to the closest dealer service center where it is currently located. When I dropped it off the service rep said he hasn't seen anything like this. Prior to this incident I had no issues with the truck and it was last serviced by the dealership on March 4, 2026.

The contact stated that the check engine warning light was illuminated. The dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure and informed the contact that a loaner vehicle would be provided if the engine failed. The failure mileage was approximately 26,700.

Toyota has not provided solutions to two of three recalls. This has been nearly a year and no solution.

My 2023 Toyota Tundra iforcemax truck has been out of commission for 56 days (since June 29, 2026). I have experienced a "shroud rub" issue which is a widely documented design flaw in 2022–2025 Tundras. It happens when pressure from the transmission lines warps the passenger-side plastic fan shroud, pushing it straight into the radiator fins until it rubs a hole right through them. The dealer (fred haas Toyota world, spring TX) has stated that they are still waiting for a new fan shroud to arrive and have no firm date when it will arrive. This is a safety issue as the vehicle sends a clear warning on the dashboard gauge cluster of the dangerous condition to over heating and advises the driver to immediately pull over, switch offthe engine and let it cool down or risk catastrophic failure.

When returning home from vacation towing my travel trailer. A warning light came on that said pull over immediately you have lost all power. I pulled over immediately and definitely had lost power and was stuck on a mountain pass. I called for a tow which took 7 hours. I called Toyota during that time and they couldn't tow me home just to the nearest dealer. My family and I had to wait for 7 hours on a small turnout on the road it was very hot that day. I had my truck towed to my local Toyota dealer and they confirmed it was the engine with metal shavings in the oil pan. Towing costs were 1102. 50 out of my pocket as Toyota would not cover.

On xxx6, while driving on the highway at approximately 89 mph and 36,714 miles, the engine misfired and the vehicle began shaking. The check engine light started flashing and a "reduced power, visit dealer" message appeared, along with a loss of motive power. The vehicle was taken to an authorized dealer on xxx at 37,032 miles. The dealer's repair order documents stored diagnostic trouble codes for random misfires, and states that freeze frame data confirmed misfires on cylinders 3, 4 and 5 at 89 mph and 2700 rpm in direct injection mode. Despite this, the repair order was closed as "no issue found. " no repair and no further diagnosis was performed. The dealer stated the condition could not be duplicated after driving the vehicle and idling it for about an hour. The vehicle is subject to an open safety recall for machining debris in the engine (NHTSA 25v767, manufacturer 25tb14), for which no remedy is available. The recall summary lists engine knocking, rough running, no-start and loss of motive power as symptoms, and instructs owners experiencing symptoms to contact their dealer. When contacted, the dealer stated the manufacturer is still developing a remedy and that the vehicle can either wait indefinitely or be picked up as is. The defect remains undiagnosed and unrepaired. The vehicle is available for inspection. The safety concern is a sudden loss of motive power at highway speed, which is the same risk identified in the manufacturer's own recall filing. No remedy has been made available more than ten months after the recall was filed. Video of the failure as it occurred, showing the check engine light flashing and the loss of power: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Recall number 25v-767 engine may stall during driving. I was told by my local tempe Toyota dealership that my engine was going to be replaced and they would contact me when my line number came up. Now I learned that Toyota can't keep up with the demand so they are going to scan vehicles to see if there is any damage. My vehicle only has 20,000 miles on it so how can a scan determine that the engine will not fail at 60k. That's like telling someone that needs a heart transplant that there heart is beating good today so they don't get the transplant. Do people need to die to make Toyota liable. Toyota knew these vehicles were bad but they were allowed to continue to sell them year after year. It is a fact the #1 main bearing is defective. I don't feel comfortable putting my family in a vehicle that can seize up while going at a high speed. Nhtsa it is your job to hold vehicle manufacturers to a high safety standard.

The contact owns a 2023 Toyota Tundra. The contact stated that while driving at an undisclosed speed, several warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with turbo boost failure. The contact was informed that the turbo boost needed to be replaced. The vehicle was repaired. In addition, the contact was informed that the failure was not associated with NHTSA campaign number: 25v767000 (engine and engine cooling); however, the part to do the recall repair was unavailable. The contact stated that the part for the recall repair had been unavailable for approximately nine months. The manufacturer was made aware of the failure, and several cases were filed. The failure mileage was approximately 41,000.

Vehicle has two open Toyota safety recalls that have remained unresolved for over a year. Nhtsa campaign 25v322 (manufacturer no. 25tb06) covers reverse lamp assembly corrosion. Nhtsa campaign 25v767 (manufacturer no. 25tb14) covers a v35a engine manufacturing defect where leftover machining debris can damage the main bearing, leading to engine knocking, rough running, no-start, or loss of drive power while driving. No engine symptoms have occurred to date. However, the vehicle is used for rideshare and delivery work, meaning passengers and cargo are regularly on board while this known defect remains unremedied. The dealership stated it could not address the engine recall and directed me to Toyota corporate. Toyota corporate opened a case and confirmed no remedy is currently available for this recall. The vehicle has not been inspected by the dealer or manufacturer, as no repair or inspection procedure has yet been provided to perform one. No warning lamps or dashboard messages have been observed. Vehicle is available for inspection upon request. Concern: a known crash-risk engine defect (loss of drive power) has been acknowledged by the manufacturer for over a year with still no completed remedy, while the vehicle continues to be operated commercially with passengers.

Toyota Tundra 2025 limited stalled at highway speeds. The vehicle flashed "parking brake support" message, but dealer says it has to do with an engine failure. Vehicle came to a grinding stop and would only advance in short spurts before dying on the side of the road. I was in the left lane of a major highway during rush hour. Luckily, traffic was behind me, and I was able to limp to the shoulder before traffic arrived. I noticed nothing prior. A loose gas cap may have prompted the system to send failure message. I haven't heard yet why it stalled. But my safety was definitely put at risk, and I was lucky to not be rearended.

The recall was issued may 2025 and still has no remedy, bulletins state anticipated remedy in 4th quarter of 2025, we are in middle of 2026, over a year since the recall was issued another recall issued November 2025 with no remedy yet.

Vehicle surges sometimes and repeatedly from a stop, with delayed acceleration; very dangerous when merging or moving from a stopped position into a flow of traffic (such as turning right on red). Vehicle sometimes will not move at all under acceleration, as if it has no gas at all. Vehicle is under recall for both of these issues related to the engine, but "no remedy available. " latest incident of surging was less than a week ago. Happens 2-3 times a day on average. Vehicle will occasionally randomly run rough at stoplights / idle speed. I have contacted Toyota regarding a buyback and they stated they "could not offer a buyback because they have not had adequate chances to fix the problem. " so they have told me they cannot fix the problem, but won't buy back the truck because they have not had a chance to fix the problem (that they cannot fix). They have since stonewalled me and no longer respond to communications.

Manufacturer recall number25tb06 NHTSA recall number25v322 in regards to the above mentioned recalls. The vehicle's reverse camera began flashing while driving forward. The r light on the gearshift was also flashing. While driving forward about 15 mph out of a parking lot, the vehicle suddenly went into reverse on it's own, locked up and would not move. I had to have the vehicle towed to the dealership. This happened around the week of June 8. The dealership says that they reset the electrical recall, we picked up the truck and it ran fine for about a week. The reverse camera and r light on the gearshift began flashing again on June 17. It did not shift itself into reverse, but the dealership requested that we bring the vehicle back. The dealership stated that Toyota has "grounded" the vehicle and does not have a fix for the recall to date and continuing to drive it is a safety hazzard. It has been sitting at the dealership since June 18 with no end in sight. The dealership and Toyota corporate continues to tell me every few days that they do not have a fix for the issues/recalls.

While traveling on us highway 95 between lewiston and riggins, idaho, a 2024 Toyota Tundra trd pro with approximately 18,000 miles experienced a sudden loss of engine power while descending a mountain grade with multiple curves. The driver reported hearing abnormal engine noises immediately before the loss of power. At the same time, the brake pedal became extremely hard to depress and the vehicle did not decelerate as expected, requiring substantially increased braking effort. The vehicle was carrying family members and was traveling on a winding downhill section of highway adjacent to steep terrain. Due to the loss of power and increased braking effort, the occupants feared the vehicle would be unable to stop safely. Fortunately, a roadside pullout area was available, and the driver was able to steer the vehicle into the pullout and bring it to a stop without a collision. The vehicle was towed to an authorized Toyota dealership for inspection. The dealership diagnosed the vehicle with a catastrophic engine failure requiring engine replacement. The failed engine remains in the possession of the dealership and should be available for inspection. Approximately five days before this incident, the vehicle had undergone routine maintenance, including an oil change and inspection at a Toyota dealership. The vehicle had also previously been presented for brake pulsation concerns and other drivability-related complaints. The vehicle was returned to service and represented as operating normally. No collision occurred and no physical injuries were reported; however, the incident created a significant safety risk because the loss of engine power occurred while descending a mountain highway and the driver experienced substantially increased braking effort while attempting to stop the vehicle.

The engine lost power and shut down at highway speeds which put myself and a passenger at risk for a crash. There were no warning lights or other symptoms before the engine shut down. After pulling the vehicle over to the side of the road, I attempted to restart the engine. The engine failed to turn over and start. The truck towed into a local dealership and is waiting inspection.

Have owned the 2025 Toyota Tundra for about 18 months. Multiple instances of delayed acceleration when stopped or almost stopped, sometimes as much as 3 or 4 seconds. Last time was in early June, 2026. This is very dangerous because when I pull out into an intersection it will start to go but then lose all power for a few seconds with traffic coming behind me. This is something Toyota needs to look into.

Three recalls have now been issued across four years post-fix engines are still failing for the new Tundra Toyota is still issuing new part numbers and design revisions for 2026 the NHTSA filing explicitly references engine configuration as a pressure driver no complete remedy exists for the second recall as of today the probability this is purely a manufacturing debris issue is effectively zero at this point. As one insider on bobistheoilguy summarized: "Toyota is not telling the public the entire extent of the issue because all vehicles with that engine are experiencing failures and because it's at least partly a design flaw issue — even the replacement motors will fail. " bobistheoilguy what Toyota has is a design that operates with insufficient margin at #1 main, which means it will continue to surface failures even in "clean" engines under the right combination of load, heat, and mileage — just at a lower rate than the heavily contaminated early production units. That's why there's no clean fix. You can't recall your way out of a physics problem. This is a engine defect. Toyota needs to buy back all these vehicles.

Engine shutdown while driving (was towing a travel trailer at the time) and after coasting to a stop the engine would not start. After 10 minutes the engine would start, but had loud knocking. My 2024 Tundra only had 31,726 miles and had to be towed to the dealership. Seems to be the known engine issues with the redesigned v6 engine. Tundra has been in the dealership for 4 weeks and was told it will require engine replacement, but do not know when the new engine will be shipped. While Toyota will perform the replacement free of charge, based on the hundreds of thousands of Tundra's being recalled for this very issue, I no longer trust this engine design (replaced or not).

I have a 2024 hybrid Toyota Tundra equipped with v35-a- fts 3. 4 l twin- turbo v6. This motor is the same engine as the non hybrid motors included in the recall. There was recently a defect information report sent out on may 20th 2026 from Toyota stating that there is an issue with the main #1 bearing and the newer motors are now being installed with upgraded new bearing indicating that all motors, hybrid or non hybrid prior to August of 2024 have this defect that could cause engine failure. The only reason this motor is not included in recall is Toyota saying that it not a safety issue because of the electrical motor is sufficient to get it off the road. I tow a boat and various trailers and feel like at highway speeds in traffic a failure of the main engine, with very limited assistance from electrical motor could cause a potential serious crash leading to serious injury or death. I am filing this to ask NHTSA to do the right thing and have Toyota to expand the recall and include the hybrids as it will only be a matter of time before before something will happen.

2024 Toyota Tundra experienced a serious safety event. While travelling on the highway at 60mph speeds in traffic when the truck suddenly blinked a loss of steering warning light then immediately blinked engine failure warning light. The truck lost power and the engine completely shut down in traffic going down a long, steep hill. I was able to reach the bottom and pull over but the truck would not restart. I had to have the truck towed to a Toyota dealership near my home.

When coming to a rolling or quick stop and then attempting to maneuver across traffic, my truck hesitates for about a full second before accelerating. This delay can create a dangerous situation for myself, other drivers, and pedestrians. I believe this is a safety issue that Toyota needs to address promptly.

I am 99% sure my vehicle is compromised via a cybersecurity incident. My emergency brake will sometimes slam for no reason, no multi media system updates have occurred for over two years, and the vehicle will randomly beep on its own, unlocking the doors. Another major issue is a recent electric harness failure that the mechanics have no idea how it happened. It cost me over 8,000. Warning lights also turn on for no apparent reason such as parking, sensors, and other traction control. I am extremely concerned with my safety. I also believe the odometer has been altered to register higher mileage.
